### How to Calculate Cement, Sand and Coarse Aggregate

Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

Learn More### Cement - Wikipedia

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is behind

Longitudinal joint spacing on two-lane and multilane concrete pavements typically is about 10 to 13 ft (3.0 to 4.2 m). This tool provides an estimate of the maximum allowable joint spacing based on the slab thickness and the subgrade/subbase used, two of the variables with the most prominent effect on joint spacing requirements.

The smallest sieve opening through which the entire amount of aggregate is permitted to pass is called the nominal maximum size. For example, for the aggregate meeting the specification limits shown below would have a maximum size of 37.5 mm (1-1/2 in.) and a nominal maximum size of 25.0 mm (1 in).
